DEVICE FOR REMOVING WASTE YARN FROM FILLING-CARRIERS.

SPECIFICATION forming part of Letters Patent No. 619,682, dated February14, 1899.

Application filed September 29, 1898. Serial No- 692,209. '(No model.)

To it whom it may concern.-

7 Be it known that I, WILLIE G. EATON, of Nashua, county ofI-Iillsborough, State of New Hampshire, have invented an Improvement inDevices for Removing Waste Yarn from Filling-Carriers, of which thefollowing description, in connection with the accompanying drawings, isa specification, like letters and figures on the drawings representinglike parts.

In that type of loom wherein provision is made for automaticallysupplying the shuttle with fresh filling upon failure or more or lesspartial exhaustion of the filling the incoming filling-carrier displacesone in the shuttle and the ejected filling-carrier falls or is directedtoa suitable pan or receptacle. These ejected filling-carriers usuallyhave a little yarn remaining upon them, as in some looms of the typereferred to-such, for instance, as shown in United States Patent No. 527,014, dated October 2, 1894the change of filling is purposely effectedwhile there is some yarn still on the ejected bobbin or filling-carrier.

Obviously such bobbins must be stripped of the yarn so remaining uponthem, and this stripping has heretofore been efiected by hand. 1

This invention has for its object the production of means formechanically stripping the filling-carriers, so that when they arefinally collected they will be clean and ready for rewinding withoutfurther handling.

Figure 1 in elevation and partial section illustrates astripping deviceembodying my invention, shown in connection with a loom; and Fig. 2 is apartial sectional view of the device on the line x 00, Fig. 1, lookingto the right.

I have herein shown my invention as used in connection with such a loomas forms the subject-matter of United States Patent No. 553,814, datedJanuary 28, 1896, to which reference may be had, and the strippingdevice is mounted on the loom side A at that side of the loom adjacentthe filling-changing mechanism. i

A stand A, secured to the loom-frame, supports an upright hopper B, intothe open top of which the ejected filling-carriers f (see dotted lines,Fig. 1) pass, the said hopper having at or near its delivery endacontracted delivery-throat b the upper concave wall 1) thereofextending from the lower edge of an inclined shelf 1) to the outer wallof the hop per. The lower or opposite wall of the throat is formed inpart by a rotatable roll' 0, mounted on a stud 0*, attached to the standA, said roll extending across the hopper, asshown in Fig. 2. Above theroll, on the inner side of the hopper and completing the throat-wall, Ihave located a combined guard and guide, shown as a concave plate b theedge 3 thereof clearing the top of the roll and being below the edge ofthe shelf b. A pinion c on the roll a is in mesh with a gear 0 rotatedin suitable manner from one of the continuously-rotating shafts of theloom, as O by or through an endless belt 0 and sheaves c 0 The surfaceof the roll may be roughened in any suitable manner or so prepared as toengage the yarn on the bobbin as the latter passes through the throat bWVhen the ejected filling-carrier, as f, enters the hopper, it isdirected by the shelf b and, guide b into the throat b through which itpasses to a box or receptacle P, Fig. 1. As it passes the stripper c,which is rotated in the opposite direction to the movement of thefilling-carrier, (see arrow 12,) the loose end of the yarn remaining onthe bobbin will be caught by and wound upon the stripper c, andconsequently unwound from the bobbin. This engagement of the yarn by thestripper refers to such filling-carriers as have been ejected with looseends. When a nearly exhausted filling-carrier is ejected, it will beunderstood that the end of the yarn is usually held by the cloth, sothat the bobbin will drop into the hopper and through its throat. Whenthe yarn is severed by a suitable threadcutter, the loose end willnaturally fall within the hopper, so as to be caught by the stripper andwound upon it. In either case the device is operative, and when thestripper is full the collected waste yarn can be readily removed, thestripper being preferably made tapering in order to facilitate suchremoval of yarn therefrom.

The plate b cooperates with the shelf 1) in guiding the filling-carriersinto the throat of i the hopper, and it also serves as a guard toprevent passage of a filling-carrier behind the stripper.

My invention is not restricted to the precise construction andarrangement herein shown and described,for,so far as I am aware, it isbroadly new to remove or strip Waste yarn from filling-carriers orbobbins by mechanical means.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a device of the class described, a hopperhaving a delivery-throat,a rotatable yarnstripper forming a portion of one wall of the throat,means to direct a filling-carrier into engagement with the stripper, anda substantially inflexible fixed guide to support the filling-carrierwhile subjected to the action of the stripper, whereby the waste yarn onthe filling-carrier will be caught by and wound upon the stripper.

2. In a device of the class described, ahopper having a contracteddelivery-throat, a rotatable stripper forming a portion of one wall ofthe throat, and means to guide fillingcarriers in the hopper to saidtl1roat,whereby the stripper may engage and wind upon itself waste yarnfrom the filling-carriers.

3. In a device of the class described, a receiving-hopper for thefilling-carriers, having a contracted deli verythroat, andyarn-stripping means located adjacent the throat, to engage the looseends of waste yarn on fillingcarriers passed through the throat andclear them of the waste yarn.

4. In a device of the class described, a hopper having a contractedthroat through which the filling-carriers pass, a rotatable, taperingstripping-roll at one side of the throat, means for rotating itoppositely to the direction of movement of the filling-carriers, acombined guide and guard above the roll at one side of thethroat-entrance, andan inclined guide at the other side, the waste yarnon the fillin g-carriers being caught by and wound upon the stripper.

5. In a device of the class described, a tapering stripping-roll havinga roughened su rface, means to rotate it, a concave plate adjacent saidroll and forming therewith a passage for the filling-carriers to passthrough, and guides to direct filling-carriers between said plate androll.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
